The plugin-cfg.xml file on the HTTP Server machine (RPS) reads WebSphere's plugin-cfg.xml file to forward requests to WebSphere. Copy the existing plugin-cfg.xml file on the RPS machine to a safe backup location and replace it with the plugin-cfg.xml file from WAS_HOME\config\cells\plugin-cfg.xml.

You can find the location of the existing plugin-cfg.xml on the RPS machine as follows:

On an IBM Http Server machine —

Open IBM_HTTP_Server_HOME\conf\httpd.conf, and search for “plugin-cfg.xml” in it to discover the location of the plugin-cfg.xml file on the RPS machine.

On a Sun ONE (iPlanet) Web Server machine —

Open Sun_ONE_HOME\servers\https-machine.domain\config\magnus.conf, and search for “plugin-cfg.xml” in it to discover the location of the plugin-cfg.xml file on the RPS machine.

If you experience any problem with the HTTP plug-in component—the component that sends requests from your HTTP server (for example, IBM HTTP Server, Apache, iPlanet, or IIS) to WebSphere—try doing the following to resolve the problem:

Review the file install_dir\logs\http_plugin.log for clues. Look up any error or warning messages in the message table.

Review the HTTP server’s error and access logs to see if the HTTP server is experiencing a problem. Following are the log files for each server:
